1 and 4 injectors were chuffing a bit. I tried tightening the 8 clamp bolts (2 for each injector) but it didn't work.

So, before they got welded in by carbon, I had the garage replace all the seals.

Autodata said 5 1/2 to 6 hours which seemed excessive based on comments I've found in a few posts on here, so I decided to make things easier for them and hopefully cheaper for me by drenching them in WD40 for a couple of days prior and also took the scuttle off.

3 hours labour later and all done @ £160, with one washer pretty bad and the others getting there. Definitely worth some prep I think to keep costs down.
